Salaah

Performing salaah with jamaat at work

Q: I work in a hospital. The nearest Musjid/Musallah is about 5-6 km away. Alhamdulillah we have permission to travel for Zuhr salaah during our lunch break (Our lunch break is 30 min, but it takes about 40min to go for Zuhr salaah and come back to work) and have been doing so for approximately the last 3 years.

However there are colleagues from other departments in the hospital who are not always able to join us for salaah. Should we request hospital management to give us a room to perform salaah with jamaat, and encourage other colleagues to join us for jamaat, or should we continue to encourage them to join us for salaah at the musjid?

Reciting an aayah incorrectly in salaah

Q: 

1. If an Imaam recited an aayah of Surah Naba incorrectly in the fardh of Esha i.e. instead of reciting لاَ يَتَكَلَّمُونَ إلّٰا مَنْ أَذِنَ لَهُ الرَّحْمٰنُ, he recited لاَ يَتَكَلَّمُونَ مَنْ أَذِنَ لَهُ الرَّحْمٰنُwill the salaah break?

2. If the salaah breaks, then if among the muqtadis there was a person who was a musaafir, should the musaafir muqtadi repeat four rakaats or two rakaats?

3. If the mistake was in Esha salaah and the Esha has to be repeated, then will a person who has performed witr after the esha salaah have to repeat the witr salaah as well? 

Taking sleeping tablets

Q: Is it permissible to use or prescribe sleeping pills? After using them, sometimes one is not in his conplete sense and sometimes says what will not usually say in public? Would Namaz be valid in this state? Can it be used if one is unable to sleep? Or can it be used sometimes when one wants to releive himself of worries?
